Field sample and data collection allow monitoring of off-site transport of pesticides and other potential pollutants. These data can then be used to make management practice recommendations.

Urbanization simulation
Laboratory rainfall simulations are performed on slopes representing different urbanization and development patterns to quantify impervious surface spatial characteristic effects on hydrology and erosion.

Field rainfall simulations are performed to determine the effects of tillage and scaling on transport of widely used herbicides with surface runoff .
